LoRa Farm Sensor Array
LoRa Farm Sensor Array — Deploy Wireless Soil Monitoring with GPS Crop Mapping
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform large-acre farmland into a data-driven operation. This kit empowers you to deploy a network of eight solar-powered soil nodes that measure moisture and temperature, each tagged with precise GPS coordinates. The data streams to a central LoRa gateway and populates a real‑time dashboard where sensor positions are mapped and crop health overlays highlight dry zones, wet patches, and temperature stress areas — giving you the same kind of insight used by commercial precision‑agriculture platforms.
What You'll Build
An 8-node LoRa wireless sensor network that transmits real‑time soil moisture, temperature, and GPS coordinates from up to several kilometres away to a central hub. The gateway processes the incoming packets and feeds a web dashboard with an interactive farm map. Crop health overlays colour-code each sensor’s reading, so you instantly see which zones need irrigation or attention, without walking the field.
What You'll Learn
- Configure RA-02 LoRa modules for long‑range, low‑power communication and link them with ESP32/Arduino Nano
- Interface resistive soil moisture sensors and waterproof DS18B20 probes for reliable field data collection
- Integrate GPS receivers to geo‑reference each sensor reading and build location‑aware dashboards
- Assemble solar‑powered nodes with TP4056 charging modules and 18650 cells for maintenance‑free deployment

Who This Kit Is For
Agritech entrepreneurs validating field‑monitoring prototypes, B.Tech ECE/EEE final‑year students working on IoT‑based agriculture projects, and Smart India Hackathon teams building precision farming solutions. Also ideal for researchers at IITs, NITs, or agricultural universities who need a ready‑to‑deploy sensor network for experiments, and for progressive farmers or FPO cooperatives eager to move beyond guesswork with their own low‑cost telemetry.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to launch the AI companion trained specifically on this kit — it will walk you through debugging step by step, and you can also reach us on WhatsApp for additional guidance.
How far can the LoRa nodes transmit in an actual farm?
With the included 433MHz antennas and line‑of‑sight above crops, expect 2–5 km in rural conditions. Dense foliage or buildings may reduce range, but the network architecture supports a star topology where the gateway can be placed centrally to cover large areas.
Do I need any license to use 433MHz LoRa in India?
No, the 433 MHz band is licence‑free for low‑power devices in India, making it ideal for farm telemetry. The kit complies with ISM band power limits.
Can I add more than eight sensor nodes later?
Yes, the gateway software is designed to support up to 24 unique node IDs. You can build additional nodes using the same RA-02 + Arduino Nano combination and simply register their IDs on the dashboard.
Eight soil nodes send moisture, temp and GPS to a LoRa gateway. Dashboard maps sensor positions with crop health overlays.
